A novel adaptive waveform design method

Modern radar systems should transmit different waveforms according to different environment. So how the transmitted waveform adapts in response to information regarding the radar environment is an important problem in radar waveform design. In this paper, based on mutual information and water-filling method, a novel adaptive waveform design method is used to obtain optimized water-filling waveform when there is no clutter. In simulation, extended target with Gaussian random process is considered. Simulation results show that the optimized transmitted signal allocates as more energy into different modes of target response as possible and the optimal radar waveform will spread its energy among most of the spectral peaks of the target response. Finally, the whole paper is summarized.
